Protective relay testing may be divided into three categories.
Protection relay test equipment.
The mentor 12 incorporates the latest designs and concepts for protective relay testing based on leading edge technology.
The doble f6150sv protective relay test equipment is a versatile solution for testing iec 61850 based protection devices and schemes.
This leads to additional testing requirements.
Universal secondary injection test set for testing all kind of protective relays and protection schemes.
Relay test solutions may be expensive propositions when software is charged separately but with megger solutions the software required to test most relays is included with the test.
In a normal industrial application periodic testing should be done at least every 2 years in accordance with nfpa 70b 2016.
The f6150sv has the highest output current of any test set on the market all within a single box.
If a fault isn t corrected early personal injuries and damage can occur.
This revolutionary product the most modern equipment of its class fulfills the requirements of the transmission departments and the commissioning of new installations.
Hzjb 1a 3 phase relay test equipment.
Haomai electric test equipment co ltd as a subsidiary of haomai electric power automation co ltd focuses on the sales and service of protection relay test system ct pt analyzer battery load unit transformer testing equipment partial discharge detector circuit breaker testing equipment etc.
Hzjb 1a 3 phase relay test equipment main features t he standard output of 4 phases of voltage and 3 phases of current it could combine various type of current or voltage conveniently and has diversity type of protective experiment.
Our test equipment is ideal for each of these life cycle phases and for any environment.
Unit protection schemes involve relays that need to communicate with each other.
Electrical power test and measurement instruments.
The purpose of protective relay equipment is to sense fault states and trip circuit breakers.
Every phase of voltage output is 120v and.
This power system simulator performs the simplest through the most complex tests.
Megger developed the first software driven protective relay test system in 1984 and we continue to provide models ranging from computer controlled with comprehensive yet simple built in touch screen user interfaces to manually operated test sets in portable and laboratory styles for every relay testing need.
In order to ensure reliable operation protective relays as well as recloser controls must be tested throughout their life cycle from their initial development through production and commissioning to periodical maintenance during operation.
Acceptance testing commissioning and maintenance testing.
The communications path between the relays is tested using suitable equipment to ensure that the path is complete and that the received signal strength is within specification.
